Why People Rush to Engage in Heroic Altruism

Why are people willing to risk their lives to help others in emergencies?

Key points

  • In terrorist attacks, there are almost always reports of heroic altruism, despite the acute danger.
  • Standard scientific theories struggle to account for such selfless and heroic acts.
  • Impulsive altruism in high-stakes situations suggests that altruism is natural to human beings.

Six years ago this week, on May 22, 2017, my home city of Manchester, England, suffered a terrorist attack. A suicide bomber detonated a homemade bomb in the foyer of an arena after an Ariana Grande concert. Twenty-three people were killed, and over 1000 were injured, most of them teenagers and children.

The attack was a tragic reminder of the brutality and destruction that emerge from the worst aspects of human nature. However, there is another side to the incident, which illustrates the best aspects of human nature.

A report into the attack, commissioned by the mayor of Manchester, noted “hundreds if not thousands of acts of individual bravery and selflessness.” More specifically, the report described “the heroic actions of some members of the public involved in the widespread provision of first aid and reassurance to the casualties as well as assisting in the portage of those casualties.”

Public members worked with police officers to carry out injured people on metal railings. Stewards formed a human wall to stop people from going toward the smoke. A man named Stephen Jones was sleeping rough near the venue and rushed in to help. He found many children covered with blood, screaming, and crying. He and a friend pulled nails out of the children’s arms—and in one case, out of a child’s face—and helped a severely bleeding woman by holding her legs in the air. Jones described, “It was just my instinct to go and help people out.”

As a paramedic named Dan Smith, who was at the scene, commented, “There were an unbelievable amount of people doing what they could to help...I saw people putting together in a way I have never seen before…The thing I will remember more than any other is the humanity that was on display.”

Danger of death

Acts of heroic altruism are almost always a feature of crises and emergency situations. When a person’s life is endangered, it is common for witnesses or bystanders to act impulsively to try to save them, even if it involves risk to their own lives. This applies to small-scale individual incidents–such as attempting to save someone from drowning or jumping down from a train platform to save someone who has fallen onto the track–and also to major disasters, such as earthquakes or airplane accidents. Such examples contradict the theory of the bystander effect, which suggests that observers are reluctant to help in the presence of other bystanders. (This theory has been largely discredited in recent years.)

One might expect such acts of heroic altruism to become less frequent as personal risk increases, but this is not the case. In terrorist attacks, there are almost always reports of heroic altruism, despite the acute life-threatening danger.

For example, in 2019, a purportedly reformed terrorist was attending an offender rehabilitation conference in London when he ran amok with two knives, quickly killing two other conference participants. The terrorist ran outside, intending to kill others. However, members of the public quickly surrounded him, wielding improvised weapons such as a fire extinguisher and a long narwhal tusk (taken from the wall of the conference hall). The group wrestled the terrorist to the ground and held him down until police officers arrived. This was even though he was wearing a suicide vest (later found to be fake). One witness described how a pedestrian “ran through traffic and jumped the central partition to confront the attacker with several others…Amazing bravery.”

The Paris terrorist attacks of November 2015 featured several incidences of altruistic heroism. At the Bataclan Hall–where 89 people were killed–a security guard named Didi risked his life to guide an estimated 400-500 people to safety, walking them back and forth through emergency exits to a nearby students’ hall of residence. A pregnant woman he guided to safety said, “My life will never be long enough to thank him for what he did. And thanks to him, my baby has a mother. We saw the worst things that night, the worst human beings ever. And then we saw the best thing" (ibid.).

Tragically, a man named Ludovico Boumbas did lose his own life through his altruism. He was eating at the Belle Equippe bar when terrorists began shooting at the terrace. Rather than diving for cover, when he saw a gunman aiming at a woman nearby, he impulsively dived before her, sacrificing his life for hers.

Explaining extreme altruism

Neo-Darwinism and evolutionary psychology theories portray humans as ruthless genetic machines only concerned with survival and reproduction. From such a perspective, altruism is problematic, especially at the extreme level described above. If human behaviour is motivated by selfishness, why are we willing to impulsively endanger our own lives for the sake of strangers? Theories such as kin selection, reciprocal altruism, “costly signaling,” or hidden egoism struggle to account for such selfless and heroic behavior.1 As economist Hannes Rusch noted in a recent paper, most studies that purport to show evidence for the above theories are only based on “low-stake” altruism.2 (After all, it’s difficult to conduct to attain ethical approval for studies of high-stake altruism.)

It is very significant that the above acts of altruism are impulsive. They occur on the spur of the moment, without any conscious deliberation. In a series of studies led by psychologist David Rand (from 2012 and 2014), a strong correlation has been established between impulsivity and altruism.3 The less time individuals have to deliberate, the more likely they are to be altruistic. A 2020 paper also concluded that heroic altruism is "intuitive" rather than the result of reflection.4

This suggests that altruism is innate to human beings. As I point out in my new book DisConnected, altruism arises from interconnection.5 There is a sense in which human beings are not separate entities. We can enter each other’s mental space and share each other’s experiences. In other words, we can empathise with one another. And empathy gives rise to altruism. As the “altruism-empathy” hypothesis developed by Daniel Batson6 suggests, altruism may sometimes have selfish motives or bring some beneficial after-effects. But “pure” altruism also arises from the human capacity for empathy.

Our capacity to sense the suffering of others gives rise to an impulse to alleviate that suffering. In a 2019 study of heroism entitled “The Making of a Hero,” the authors noted that one of the main characteristics of heroes is “an expansive sense of empathy, not simply with those who might be considered 'like them' but also those who might be thought of as 'other.'”7

The brutality of terrorism arises from disconnection—the ideological abstraction that divorces adherents to the reality and value of other human beings. In contrast, heroic altruism arises from a fundamental connection between human beings, which enables empathy and triggers an impulse to save the lives of others.
